Dorian Vallejo is a wonderful artist living in New Jersey who has collected together a volume of his work, "Drawings: Inspired By Life," available at http://www.drawingsfromlife.com/Pages/Book/Book_Page.html . The book is $38.99 plus shipping (this sounds like a fantastic bargain to me).
I can't wait to get a copy of this book - I've been a fan of his for a long time. He has been a huge inspiration to me in my own work. What a treat to see all these in one volume. Bravo, Dorian!
